You need to give us the passage so we can answer
I would say the second option.
Can you provide a picture please and thank you?
The sentence in which the verb agrees with the subject is: The orchestra performs after this dance routine. The correct answer is option A. The subject of the sentence is the word "orchestra". This is an example of a collective noun, meaning, a group of musicians playing together. Since it is labeled as a group and only one group is mentioned in the sentence, then it should take the singular form of the verb which is "performs".
